HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 231, 124 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 231, 124 is 1 the largest number which exactly divides all the numbers i.e. where the remainder is zero. Let us get into the working of this example.
Consider we have numbers 231, 124 and we need to find the HCF of these numbers. To do so, we need to choose the largest integer first and then as per Euclid's Division Lemma a = bq + r where 0 ≤ r ≤ b
Highest common factor (HCF) of 231, 124 is 1.
HCF(231, 124) = 1
HCF of 231, 124 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 231, 124 is 1.
Highest Common Factor of 231,124 is 1
Step 1: Since 231 > 124, we apply the division lemma to 231 and 124, to get
231 = 124 x 1 + 107
Step 2: Since the reminder 124 ≠ 0, we apply division lemma to 107 and 124, to get
124 = 107 x 1 + 17
Step 3: We consider the new divisor 107 and the new remainder 17, and apply the division lemma to get
107 = 17 x 6 + 5
We consider the new divisor 17 and the new remainder 5,and apply the division lemma to get
17 = 5 x 3 + 2
We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get
5 = 2 x 2 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 231 and 124 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(17,5) = HCF(107,17) = HCF(124,107) = HCF(231,124) .
